GAS-VALVE REGEPTACLE.

Application led February 28, 1923. Serial No. 621,857.

This invention rela-tes to gas fixtures of the character employed with household service piping.

In gas service piping throughout buildings and residences, it is customary to provide in theseparate rooms, gas cocks to which iiexible tubing may be attached for serving stoves for temporary heating, or for the service of 1 gas to various other appliances. In the installation of such means for providing temporary service of gas appliances, a nipple is extended up through the floor or out through the wall near the base board and a. hose yattachment gas cock screwed thereupon. yThis gas cock, by nature of the construction employed, projects-outwardly yinto the room and presents a detraction to the general appearance of the room besides, and being unsightly in appearance is in the way.

It isy an object of my invention to provide a means whereby a room may be served by a gas connection so that gas appliances may be lused in the room, without visibility of the gas cock or its projection from the wall of the room.

It is a further object of the invention to provide this means in the form of a receptacle which may be set into the wall with the front thereof flush with the surface of the wall and having means of access into the interior of the receptacle whereby the hose may be attached to the improved form of gas cock I employ, and whereby the valve may be operated.

The especial advantages of my invention kand further objects thereof will be made evident hereinafter.

Referring to the drawing which is for illustrative purposes only:

Fig. 1 is a perspective view showing the utility of the invention.

Fig. 2 is a vertical cross section through the invention as shown in Fig. 1.

Fig. 3 is a. face view of the receptacle with ythe valve disposed therein, the receptacle having the cover removed therefrom.

In Fig. 1 of the drawing, 11 indicates a wall having a gas outlet receptacle 12, embodying the features of my invention, mounted therein at a point slightly above the base board 13. The customary employment of such receptacle is for the attachment of a exible hose 14 for conveying gas to a portable heater suchas shown at 15, as Such heaters are only used templorarily. 1t

is desirable that the receptacle 12 be as inconspicuous as possible, and as hereinbefore stated my invention eliminates the necessityv of outstanding gas cocks such as now eniployed.

Fig. 2 illustrates the interior construction of the receptacle 12 which consists of a metal box 17 which may be set into the wall 11 so that the front thereof will be in a plane with the surface of the plaster or other wall iin` ish 19. This box 1i' is provided with inwardly extending tongues 2O having threaded openings 21 therein whereby a cover plate 22 may be attached by meansy of screws 23. An opening 24 is provided in the cover through which the attachment end 25 of the flexible hose 14 may be inserted and forced upon the nozzle 26 of the gas cock/2T my invention provides, and an opening 29 is also provided in the cover in a` position opposite to the valve stem 3() in order that a suitable key or wrench 31 may engage the end 32 of the stem 30.

' The cock 27 provides a threaded projection 35 which may be screwed into a sleeve coupling 36 mounted upon the upper end of a gas riser 37 and has the portion 33 thereof prepared for the application of a wrench for the purpose of screwing the cock A 27 into the coupling 36. This wrench engaging portion 38 is preferably hexagonal in form. The nozzle 26 extends upwardly from the valve body 39 in the form of a gooseneck as indicated at 40, and an opening 41 as indicated in Fig. 2 extends centrally through the threaded projection 35 and through the nozzle 26 to provide a gas passage, the flow of gas through which is controlled by the valve plug 43 from which the valve stem 30 extends.

It will be noticed that the gooseneck dips rearwardly and then projects forwardly in a horizontal plane so that the portion thereof to which the hose is attached extends at right angles to the pipe 37 to which the valve is attached. This construction provides an ample length of the end 45 of the nozzle upon which the rubber hose attachment member 25 is forced without requiring an unusual depth of the box 17, and also permits the valve to be rotated upon the axis A-A within a box of minimumwidth for the purpose of screwing into the coupling 36. It will be noticed that the forward extension than the distance from the axis A-A to the hael; 4J otv the hoi; li, therefore allowinga free rotation of' the eoel; therein.

It iS preferahle as shown in 2 and 3 to einplov a coupling' 3G in the installation of the device as it is ensztoniary tor the plninher to Close npon inotallation the endu ol all risers so that dirt will not ,fret into the pipes during' the completion ot the eonfstrnetion ot the building. rllhis is aeeoni'plislied hy plugs and caps. rI-he ot a cap, however, in this ease iinde... able, ae in removing the cap preparatoi)v tothe plaeinjY ot' the cool; 2T, loire-i' joints in the pipe may he nnserewed. In the conetrnction shown, it is possible to grip 'the upper end ot the con' plint` 36 with a wrench While the plngis hqing uneeiened theretroni, therefore aceoniplishingi' the oileiiing.l ot' the nppervend olf the` pipe Without liahility oi" unserening;` lower joints in the piping.

lVhile in the hereinhelore.description and the drawing I havey described and shown a preferred 'orin o't` nip' invention it is to` he understood that the scope thereof is subject onlyv to the limitation ot the following elaiins.

l elaini as in),Y invention:

l. In combination with a wall having an opening therein, a receptacle adapted to he set into the opening in the Wall, a cofferplate for said receptacle in fixed relation to said Wall` and said receptacle and covering the opening in the wall, a supply pipe extending into said receptacle, a Valve ineinher on Said supply pipe and in Said recept-:1- ele haring a 'li'orwartll extending attaelinient portion, said attachment portion heilig supported h i.' a gmisenechV torniation extending; rearwardlj.'v troni the longitudinal axis ot Said valve so as to perniit the rotation ol' Said valve and attachment structure in a niinironin epaee .rholl)V hehind said plate, said Cover plate haring' an opening therein through which a tnlnilar ineinher may he connected to said attachment portion o't the ralre ineinher and haring' an openingtherein through which said iali'e. mayv he operated.

In combination nith a n'all having an openingr therein, a gas ontlet tilting' coinprising: a *faire portion and a tnhe attachnient portion, Said attachment portion exteiioing substantially perpendienlarl)v with reSpeet to said valve. port-ion and joined therewith by a gooseneek extending rearwardly troni tlielongituclinal axis ot said ralfe so as to permit rotation of Said fitting in a ininiinuni space, and a cover plate for .wid titting over the openingr in the Wall in lifted relation thereto having openings therein through which. a hose Connection may be inade tovsaid attachment portion and the valve operated.
